Ensuring a desired distribution of images in a multimedia document utilizing facial signatures

ABSTRACT

A method, system and computer program product for ensuring a desired distribution of images in a multimedia document (e.g., yearbook, slideshow). A desired distribution of facial signatures in a multimedia document to be created by the user is received. Upon receiving an image to be added to the multimedia document by the user, a facial signature for a face detected in the image is generated. The current number of instances of the facial signature in the multimedia document is then determined. A determination is then made as to whether the current number of instances of the facial signature meets the desired distribution. An indication is then provided to the user as to whether the current number of instances of the facial signature meets or does not meet the desired distribution. In this manner, the user can ensure a desired distribution of images in the multimedia document.

TECHNICAL FIELD

The present invention relates generally to creating multimediadocuments, and more particularly to ensuring a desired distribution ofimages in a multimedia document (e.g., yearbook, slideshow, video,website) utilizing facial signatures.

BACKGROUND

Generating a multimedia document, such as a yearbook or slideshow, thatincludes a set of images that is representative of all the individualsthat belong to a group (e.g., sports team, class, school) is difficult,especially when the size of the group is large. For example, it takes alot of effort and time in creating a yearbook for the graduating classof a high school that includes pictures of class members and schoolactivities (e.g., sports). The creator(s) of the yearbook may want toensure that a particular class member is not overly or inadequatelyrepresented in comparison to the other class members in order to providefairness and increase member enjoyment. For example, the creator(s) ofthe yearbook may want to ensure that the yearbook does not include manyimages of a particular class member (e.g., twenty pictures of anindividual) while only including a single image of another class member.However, the creator(s) of the yearbook may have hundreds or thousandsof images of hundreds of class members to choose to include in theyearbook. As a result, it may be overwhelming for the creator(s) of theyearbook to ensure that each class member is adequately represented inthe yearbook and that there are not some class members that are overlyrepresented in the yearbook.

Currently, a multimedia document, such as a slideshow, may be generatedby selecting an image for inclusion in the slideshow, where the imagehas associated facial detection information. A face location isdetermined in the selected image based on the facial detectioninformation and the selected image is cropped based on the determinedface location to generate a cropped image depicting the included face.The cropped image is inserted into a slide associated with theslideshow. However, there is not currently an approach in ensuring aspecific distribution of images in the slideshow, such as ensuring aparticular member of a group is not overly or insufficiently representedin the slideshow.

Furthermore, a multimedia document, such as a yearbook, may be designedand created utilizing a facial recognition module for identifying asubject in a photo and tagging the photo with an identity of thesubject. Identifying the subject may include comparing the photo to aplurality of previously tagged photos to identify the subject. However,there is not currently an approach in ensuring a specific distributionof images in the yearbook. For example, there is not currently anapproach in ensuring that each individual in the class includes aminimum number of images in the yearbook. Neither is there currently anapproach in ensuring that there is a certain percentage of images out ofthe total number of images in the yearbook of a particular individual inthe class.

Therefore, there is a need in the art for ensuring a desireddistribution of images in a multimedia document (e.g., yearbook,slideshow, video, website).

DETAILED DESCRIPTION

The present invention comprises a method, system and computer programproduct for ensuring a desired distribution of images in a multimediadocument (e.g., yearbook, slideshow, video, website). In one embodimentof the present invention, a desired distribution of facial signatures ina multimedia document to be created by the user is received. Forexample, the user may specify that all facial signatures should have 5to 10 occurrences in the multimedia document. Upon receiving an image tobe added to the multimedia document by the user, a facial signature fora face detected in the image is generated, such as by using a facialrecognition algorithm. The current number of instances of the facialsignature in the multimedia document is then determined. The desireddistribution of the facial signature (the facial signature generated) isdetermined based on the received desired distribution of the facialsignatures in the multimedia document. For example, the desireddistribution of the facial signatures in the multimedia document mayindicate that the number of images of such a facial signature to beincluded in the multimedia document is to correspond to the averagenumber of images of the other facial signatures used in the multimediadocument. A determination is then made as to whether the current numberof instances of the facial signature meets the desired distribution. Anindication is then provided to the user as to whether the current numberof instances of the facial signature meets or does not meet the desireddistribution. If the number of instances of the facial signature doesnot meet the desired distribution, then images from a set of sourceimages with a facial signature that match the generated facial signaturemay be provided to the user to be added to the multimedia document ifthe current number of instances of the facial signature is below thedesired distribution. Alternatively, images from the multimedia documentwith a facial signature that match the generated facial signature may bedisplayed to the user to be removed from the multimedia document if thecurrent number of instances of the facial signature is above the desireddistribution. In this manner, the user can ensure a desired distributionof images in the multimedia document (e.g., yearbook, slideshow, video,website).

As stated in the Background section, generating a multimedia document,such as a yearbook or slideshow, that includes a set of images that isrepresentative of all the individuals that belong to a group (e.g.,sports team, class, school) is difficult, especially when the size ofthe group is large. For example, it takes a lot of effort and time increating a yearbook for the graduating class of a high school thatincludes pictures of class members and school activities (e.g., sports).The creator(s) of the yearbook may want to ensure that a particularclass member is not overly or inadequately represented in comparison tothe other class members in order to provide fairness and increase memberenjoyment. For example, the creator(s) of the yearbook may want toensure that the yearbook does not include many images of a particularclass member (e.g., twenty pictures of an individual) while onlyincluding a single image of another class member. However, thecreator(s) of the yearbook may have hundreds or thousands of images ofhundreds of class members to choose to include in the yearbook. As aresult, it may be overwhelming for the creator(s) of the yearbook toensure that each class member is adequately represented in the yearbookand that there are not some class members that are overly represented inthe yearbook. Therefore, there is a need in the art for ensuring adesired distribution of images in a multimedia document (e.g., yearbook,slideshow, video, website).

The principles of the present invention provide a means for ensuring adesired distribution of images in a multimedia document by utilizingfacial signatures as discussed below in connection with FIGS. 3-4 and5A-5B. FIG. 3 is a flowchart of a method for establishing a set offacial signatures to be compared with facial signatures of the facesdetected in images added to a multimedia document using a set of sourceimages and rules regarding identifying facial signatures in the set ofsource images. FIG. 4 is a flowchart of a method for establishing a setof facial signatures to be compared with facial signatures of the facesdetected in images added to a multimedia document using a training setof desired facial signatures. FIGS. 5A-5B are a flowchart of a methodfor ensuring a desired distribution of images in a multimedia document.

As stated above, FIG. 3 is a flowchart of a method 300 for establishinga set of facial signatures to be compared with faces detected in imagesadded to a multimedia document using a set of source images and rulesregarding identifying facial signatures in the set of source images inaccordance with an embodiment of the present invention.

Referring to FIG. 3, in conjunction with FIGS. 1-2, in step 301,computing device 101 receives a set of source images. These sourceimages may or may not be included in the multimedia document to becreated by a user of computing device 101. These source images are to beused to generate a set of facial signatures that will be compared withfacial signatures of the faces detected in images added to themultimedia document as discussed further below.

In step 302, computing device 101 receives rules regarding identifyingfacial signatures in the set of source images. For example, there couldbe a rule that images with more than a particular number of faces (e.g.,a group photograph with a large number of individuals) do not need to beanalyzed. In another example, there could be a rule to group imagescontaining a specific facial signature together. In a further example,contiguous images containing a specific facial signature (e.g., a spacesignature across the document) could be disallowed. These rules areexemplary and the principles of the present invention are to include anyrules that may be used to specify which images may be analyzed toidentify facial signatures.

In step 303, computing device 101 identifies unique facial signatures inthe set of source images. In one embodiment, computing device 101identifies unique facial signatures in the set of source imagesutilizing a facial recognition algorithm.

In step 304, computing device 101 stores the identified unique facialsignatures in a set of facial signatures to be compared with the facialsignatures of the faces detected in the images added to the multimediadocument as discussed further below in connection with FIGS. 5A-5B.

In step 305, computing device 101 receives a desired distribution offacial signatures in a multimedia document to be created by the user ofcomputing device 101. For example, the user may specify that all facialsignatures should have 5 to 10 occurrences in the multimedia document.In another example, the user could assign weights to specific facialsignatures in the set of facial signatures that are displayed to theuser (e.g., via display 215). Such weights may be used to determine howmany of each facial signature should occur in the multimedia document.In a further example, the default distribution of the facial signaturesin the multimedia document is to be equal if the user does not provideany input.

In an alternative embodiment, the set of facial signatures to becompared with facial signatures of the faces detected in images added toa multimedia document may be established using a training set of desiredfacial signatures as discussed below in connection with FIG. 4.

FIG. 4 is a flowchart of a method 400 for establishing a set of facialsignatures to be compared with facial signatures of the faces detectedin images added to a multimedia document using a training set of desiredfacial signatures in accordance with an embodiment of the presentinvention.

Referring to FIG. 4, in conjunction with FIGS. 1-2, in step 401,computing device 101 receives a training set of images representing thedesired facial signatures. In such an embodiment, the training set maybe used to assist computing device 101 to know which facial signaturesare to be included in the multimedia document to be created by the user.

In step 402, computing device 101 stores the desired facial signaturesin a set of facial signatures to be compared with the facial signaturesof the faces detected in the images added to the multimedia document asdiscussed further below in connection with FIGS. 5A-5B.

In step 403, computing device 101 receives a desired distribution offacial signatures in a multimedia document to be created by the user ofcomputing device 101. As discussed above, for example, the user mayspecify that all facial signatures should have 5 to 10 occurrences inthe multimedia document. In another example, the user could assignweights to specific facial signatures in the set of facial signaturesthat are displayed to the user (e.g., via display 215). Such weights maybe used to determine how many of each facial signature should occur inthe multimedia document. In a further example, the default distributionof the facial signatures in the multimedia document is to be equal ifthe user does not provide any input.

The images, such as images of class members in a class, areappropriately distributed in a multimedia document (e.g., yearbook)using the desired distribution of facial signatures as discussed belowin connection with FIGS. 5A-5B.

FIGS. 5A-5B are a flowchart of a method 500 for ensuring a desireddistribution of images in a multimedia document (e.g., yearbook,slideshow, video, website) in accordance with an embodiment of thepresent invention.

Referring to FIG. 5A, in conjunction with FIGS. 1-4, in step 501,computing device 101 receives an image to be added to the multimediadocument.

In step 502, computing device 101 inspects the image for instances offaces (faces of individuals).

In step 503, computing device 101 generates a facial signature for aface detected in the image. In one embodiment, computing device 101generates a facial signature for a face detected in the image utilizinga facial recognition algorithm. In one embodiment, if computing device101 cannot generate a facial signature for the face detected in theimage utilizing a facial recognition algorithm, then computing device101 may determine if the face detected in the image is tagged therebyindicating a particular individual and determine if the known individualhas an associated facial signature. In one embodiment, such facialsignatures are stored in database 102.

In step 504, a determination is made by computing device 101 as towhether there is a match between the generated facial signature with afacial signature from the set of facial signatures (discussed above inconnection with steps 304 and 402).

If there is not a match with a facial signature in the set of facialsignatures, then, in step 505, the generated facial signature is addedto the set of facial signatures.

In step 506, computing device 101 sets a value of a counter associatedwith the facial signature added to the set of facial signatures to avalue of one. In one embodiment, the counter is implemented in software(e.g., application 204). In another embodiment, the counter isimplemented in hardware or a combination of hardware and software.

If, however, there is a match with a facial signature in the set offacial signatures, then, in step 507, computing device 101 increments acounter associated with the facial signature. In this manner, the numberof instances of the facial signature in the multimedia document will beknown. Furthermore, by utilizing a counter, a mapping of the person'sidentity to the facial signature is not required thereby preserving theprivacy of the individual. In one embodiment, the counter is implementedin software (e.g., application 204). In another embodiment, the counteris implemented in hardware or a combination of hardware and software.

Upon setting a value of a counter associated with the facial signatureadded to the set of facial signatures to a value of one in step 506 orupon incrementing the counter associated with the facial signature instep 507, in step 508, computing device 101 determines the currentnumber of instances of the facial signature in the multimedia document.For example, the current number of instances of the facial signature inthe multimedia document will be equal to the value of the counterdiscussed in connection with steps 506, 507.

In step 509, computing device 101 determines the desired distribution ofthe facial signature (facial signature generated in step 503) based onthe received desired distribution of the facial signatures in themultimedia document (see steps 305 and 403). For example, the desireddistribution of the facial signatures in the multimedia documentreceived in steps 305 and 403 may indicate that the number of imageswith the facial signature generated in step 503 to be included in themultimedia document is to correspond to the average number of images ofthe other facial signatures used in the multimedia document.

In step 510, a determination is made by computing device 101 as towhether the current number of instances of the facial signature (facialsignature generated in step 503) meet the desired distribution.

If the current number of instances of the facial signature (facialsignature generated in step 503) meets the desired distribution, then,in step 511, computing device 101 provides an indication that thecurrent number of instances of the facial signature (facial signaturegenerated in step 503) meets the desired distribution. For example,computing device 101 may issue a notification (e.g., textualnotification with a green color) to the user indicating that the currentnumber of instances of the facial signature (facial signature generatedin step 503) meets the desired distribution upon the user adding theimage to the multimedia document.

Referring to FIG. 5B, in conjunction with FIGS. 1-4, if, however, thecurrent number of instances of the facial signature (facial signaturegenerated in step 503) does not meet the desired distribution, then, instep 512, computing device 101 provides an indication that the currentnumber of instances of the facial signature (facial signature generatedin step 503) does not meet the desired distribution. For example,computing device 101 may issue a notification (e.g., textualnotification with a red color) to the user indicating that the currentnumber of instances of the facial signature (facial signature generatedin step 503) is below the desired distribution upon the user adding theimage to the multimedia document. That is, computing device 101 mayissue a notification indicating that additional images with thecorresponding facial signature need to be added to the multimediadocument to reach the desired distribution. In another example,computing device 101 may issue a notification (e.g., textualnotification with an orange color) to the user indicating that thecurrent number of instances of the facial signature (facial signaturegenerated in step 503) is below the desired distribution upon the useradding the image to the multimedia document. That is, computing device101 may issue a notification indicating that images with thecorresponding facial signature need to be removed from the multimediadocument to reach the desired distribution.

In step 513, computing device 101 provides images from the set of sourceimages (received in step 301) with a facial signature that match thegenerated facial signature (generated in step 503) to the user to beadded to the multimedia document if the current number of instances ofthe facial signature (facial signature generated in step 503) is belowthe desired distribution or displays the images from the multimediadocument with a facial signature that match the generated facialsignature (generated in step 503) to the user to be removed from themultimedia document if the current number of instances of the facialsignature (facial signature generated in step 503) is above the desireddistribution. For example, if the desired distribution of the generatedfacial signature is to have four images with the corresponding facialsignature in the multimedia document and there are only two such imagesin the multimedia document, then computing device 101 may provide anindication that additional images with the corresponding facialsignature need to be added to the multimedia document. Furthermore,computing device 101 may identify images from the set of source imagesthat match the generated facial signature (generated in step 503), suchas by using a facial recognition algorithm, that have not yet been addedto the multimedia document thereby providing the user an opportunity toadd additional images with the corresponding facial signature to themultimedia document to meet the desired distribution. In anotherexample, if the desired distribution of the generated facial signatureis to have four images with the corresponding facial signature in themultimedia document and there are five such images in the multimediadocument, then computing device 101 may provide an indication thatimages with the corresponding facial signature need to be removed fromthe multimedia document. Furthermore, computing device 101 may identifyimages from the multimedia document that match the generated facialsignature (generated in step 503), such as by using a facial recognitionalgorithm, that may be removed from the multimedia document therebyproviding the user an opportunity to remove images with thecorresponding facial signature from the multimedia document to meet thedesired distribution.

In this manner, the user can ensure a desired distribution of images inthe multimedia document (e.g., yearbook, slideshow, video, website).

Upon providing an indication that the current number of instances of thefacial signature (facial signature generated in step 503) meets thedesired distribution in step 511 or upon executing step 513, in step514, a determination is made by computing device 101 as to whether theuser provides additional images to be added to the multimedia document.If the user has additional images to be added to the multimediadocument, then computing device 101 receives an additional image to beadded to the multimedia document in step 501.

If, however, the user has completed the creation of the multimediadocument, then, in step 515, computing device 101 exports the multimediadocument to a desired format.

In step 516, computing device 101 generates a summary of the facialsignature distribution in the multimedia document for the user.
